Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for osteoarthritis, such as joint replacement and external devices, are invasive, lack durability, and fail to address the unique energy absorption and movement functions of anatomical joints, leading to limited effectiveness in managing joint pain and mobility.
Innovation Solution
Implantable assemblies with flex members that absorb energy by deflecting, bending, or twisting to reduce load on anatomical joints, allowing for relative axial rotations and variable load reduction, specifically designed for synovial joints like the knee.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If joint replacement or external devices are used to treat osteoarthritis, then joint pain management is achieved, but the treatment becomes invasive and lacks durability
Solution Approach 1:
The invention divides the treatment function into two separate components: an internal implantable energy absorbing assembly that provides durable mechanical energy absorption, and an external adjustable device that provides temporary support and modulation. This segmentation allows the permanent durable component to remain implanted while the external component can be adjusted or removed, reducing overall invasiveness while maintaining reliability
Solution Approach 2:
The invention introduces an intermediary energy absorbing assembly that is implanted internally to handle mechanical energy absorption, while external devices serve as adjustable mediators that can be tuned or removed. This intermediary approach provides a durable internal solution without requiring fully invasive joint replacement, as the external components can be non-invasively adjusted
2Stability of the object's composition
If external devices are used to support anatomical joints, then joint stability is improved, but the devices lack durability and require continuous external use
Solution Approach 1:
The invention performs preliminary action by implanting the energy absorbing assembly internally before the need for continuous external support becomes necessary. The implanted device is pre-positioned to provide durable mechanical energy absorption, reducing the need for continuous external device use and providing long-term joint stability
Solution Approach 2:
The implanted energy absorbing assembly provides self-service by autonomously absorbing mechanical energy and reducing loads on the joint without requiring continuous external adjustment or monitoring. The device is designed to function independently within the body, providing durable stability without requiring ongoing external intervention
3Force
If traditional treatments are used for osteoarthritis, then joint support is provided, but they fail to address the unique energy absorption and movement functions of anatomical joints
Solution Approach 1:
The invention applies dynamics by designing the energy absorbing assembly with flex members that can deflect, bend, or twist to dynamically absorb mechanical energy while accommodating the natural movement functions of the anatomical joint. The external device can also be adjusted to modulate support forces, providing adaptable joint support that responds to varying movement requirements
Solution Approach 2:
The invention utilizes parameter changes by allowing the external device to be adjusted to modify support forces and energy absorption characteristics. The flex members in the implanted assembly can also change their mechanical properties through deflection and deformation, adapting to different joint movement phases and providing versatile support that addresses both energy absorption and movement functions
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The implantable assemblies effectively reduce pain and improve joint mobility by absorbing a portion of the load experienced during movement, providing a minimally invasive solution that complements the natural motion and energy absorption functions of anatomical joints.
Implementation Method 1
a first flex member, the first flex member configured to deflect, bend or twist to absorb energy transferred from the first component to the second component
Implementation Method 2
the joint comprises a compliance member mounted between end portions of the first and second components

AI summary
Implantable assemblies for manipulating energy transferred by members defining an anatomical joint, and methods of implanting and using. The members of the anatomical joint collectively define a path of motion. An assembly includes a first component configured to be attached to a first member of the anatomical joint; a second component configured to be attached to a second member of the anatomical joint; and a joint joining the first and second components. The first component includes a first flex member and the second component includes a second flex member. The first and second flex members are configured to flex to absorb energy transferred by the members of the anatomical joint.
